It has a nasty tendency to haze the plastic VERY badly (as in, it will make the lenses nearly opaque). If you're trying to restore a shine to the plastic, very judicious and careful application of a torch (yes, an open flame) can buff out mild scratches in the frames and lenses. I've used this technique to good effect on motorcycle helmet face shields before. Start about six inches or so back from the surface, and work at an angle. It helps if you have a light set up so you can see the haze begin to polish out as the heat does its job. Whatever you do, do NOT let the flame linger more than about half a second in any one spot, or you'll boil the plastic and get air bubbles in it. (Yep, did that by accident too.) cl Be careful with acetone around plastic safety glasses. It has a nasty tendency to haze the plastic VERY badly (as in, it will make the lenses nearly opaque).
